Sherlocking Method: Cracking UPPCS 2024 Prelims MCQs

The Sherlocking method is a way to crack prelims multiple-choice questions using three things: a strong command over basic sources, logical reasoning applied on top of them, and exhaustive previous year question (PYQ) analysis, rather than chasing new sources or new modules. In this session Neil Sir applies Sherlocking to the UPPCS 2024 Prelims paper, walking through real questions to show that the same principles that work for UPSC also work for state PCS exams. He frames the exam as an optimization problem: you cannot guarantee a correct answer from memory alone, but you can give yourself the best possible shot.

Key takeaways

• Sherlocking means basic sources plus logical reasoning plus PYQ analysis; you do not need to keep running after new sources or modules.
• The same heuristics that clear UPSC also clear state PCS like UPPCS, the techniques carry across commissions.
• "Play the options, not the question": check which statements are coherent and which stack multiple factual claims that are easy to get wrong.
• Treat prelims as an optimization problem; any heuristic with a better than 50% hit rate is worth using, because nobody can give you a guarantee.
• Speed matters: many questions, especially match-the-pairs, can be done in about 20 seconds by confirming one or two anchor matches.
• Memory has a hard limit while knowledge is unlimited, so use mnemonics and association to rely on rote recall as little as possible.

What is the Sherlocking method?

Sherlocking, Neil Sir explains, is just a fancy term for a simple idea: all you really need is a good basic source, the application of logical reasoning on top of it, and exhaustive previous year question analysis done over and over again. If you have those three things in place, you do not need to keep buying new modules or hunting for ever more exhaustive resources.

Why you cannot memorise everything

A recurring theme is the limit of memory. History, current affairs and the rest are dense, and it is simply not possible to find a resource that covers every statement, let alone commit all of it to memory. The smarter route is to hold an overarching understanding of a topic and reason your way to the answer. Knowledge is unlimited; memory is not, so lean on recall as infrequently as you can.

Play the options, not the question

A central heuristic is to read the answer options for internal coherence rather than treating each statement as an isolated fact to be verified.

• Justice Party question: If you know the broad nature of the Justice Party, that it opposed Congress as a Brahmin-dominated organisation, then the linked statement (that it sought communal representation for non-Brahmins, much as earlier reforms had for Muslims) flows as a logical extension. One being true makes the second follow, leading to the marked answer.
• First woman Supreme Court judge question: The statements that she was the first woman judge of the Supreme Court and the first Muslim woman to enter the higher judiciary are coherent and go together. The separate statement about her serving as Governor of Kerala from 1997 to 2001 carries two distinct facts, so its likelihood of being fully correct is lower, and there is no "none of the above" option to fall back on.

As Neil Sir borrows from the character Harvey Specter, "do not play the odds, play the man." In prelims, that means playing the options, not the question.

Likelihood: statements stacked with facts are riskier

The more independent factual claims a single statement bundles together, a place and a date and a number, the higher the chance one of them is wrong, which lowers the probability that the whole statement is correct.

• India-Indonesia 7th Joint Defence Cooperation Committee meeting: The statement about enhancing collaboration in defence industry, maritime security and multilateral cooperation is logically coherent, there is no reason to negate it. The statement pinning the meeting to a specific city and a specific date stacks a place and a date that could be almost anything, so its likelihood drops and it can be eliminated.
• MATES (Mobility Arrangement for Talented Early-professionals Scheme): Here the context lives inside the name itself. "Mates" is the colloquial Australian way of addressing someone, so the Australia link is coherent. "Mobility Arrangement" implies something temporary, up to two years, rather than a permanent visa; "early professionals" fits an 18 to 30 age band; and "talented" fits skills in specific fields of study. Read with that context, both statements hold.

Speed, association and mnemonics

• Match-the-pairs (revolts, Nor'westers / Kal Baisakhi in West Bengal): You often need just one confirmed match to reach the correct option. Mark the pairing you are sure of, and roughly 90% of the time you land on the right answer. Aim to solve such questions within about 20 seconds.
• Mnemonics: The taxonomy sequence Kingdom, Phylum, Class, Order, Family, Genus, Species is locked in with a phrase like "Kevin Peterson Cuffs GS." Make your own; mnemonics work like a champ.
• Pulmonary vein: The only vein carrying oxygenated blood. "Pulmonary" points to the lungs, and lungs deal with oxygen, so the answer is highly likely. This is informed association, not a blind guess.
• Cannes "Un Certain Regard" best actress: A mainstream Bollywood win would have been widely publicised, and these awards favour artistic, story-driven films, so the unfamiliar option is the most likely one.

Assertion-reason and the examiner's constraint

• Shivaji and the big Deshmukhs (assertion-reason): The reason, that these Deshmukhs wanted to remain feudal lords rather than back an independent Maratha state, is coherent and actually explains the assertion, so both are true and the reason is the correct explanation. Neil Sir adds that commissions, unlike some coaching institutes, usually do not use a "double trap," which makes a coherent assertion-reason pair highly likely to be correct.
• Examiner's constraint (chronology questions): The examiner only holds the correct answer and must fabricate the wrong options around it. So in sequencing questions, the element that repeats across the options is often the anchor to lean on. It is a deliberately "silly" heuristic, but it works at times in both PCS and UPSC.

Who should watch this

This session is for UPPCS, UPSC and other state PCS aspirants who want to push up their prelims accuracy without endlessly adding new sources. It is especially useful for anyone who freezes the moment they do not "know" a fact and needs a reasoning-first attempt strategy that keeps them in the game across history, polity, current affairs and science questions.

Closing thoughts

The Sherlocking method ultimately rests on three habits: command over your basic sources, the discipline to reason on top of what you know, and relentless previous year question analysis, not only from UPSC but from other commissions too. Treat the paper as an optimization problem, look for the shortest coherent route to each answer, and use every heuristic that beats a coin toss.
